Frequently Asked Engineering Questions
Technical answers regarding dosing tolerances, cGMP compliance, viscosity handling, and plant integration for the Inner Plug / Cap Pressing Unit.
The Inner Plug / Cap Pressing Unit maintains a repeat dosing accuracy of Zero liquid spillage across its operating range of Plug Dia 10–50 mm. Honed positive-displacement cylinders, tight-tolerance Teflon seals, and positive cut-off shutoff nozzles eliminate cavitation, stringing, and meniscus variation under continuous production.
This unit is engineered for products including Eye drop & nasal drop inner plug insertion, Liquid oral drops dropper inserts, Essential oil orifice reducers, serving industries such as Pharmaceutical, Cosmetics / Toiletry, Oil, Food & Beverages. For foaming or surface-active liquids, pneumatic bottom-up diving nozzles enter the container and lift in sync with the fluid rise to prevent aeration. For thick creams and pastes, positive displacement rotary cut-off valves provide clean transfer.
Yes. All product contact components are fabricated from certified sanitary SS 304 / Food grade PU belt (with mirror-polish Ra < 0.4 µm). Sanitary tri-clover ferrule couplings allow tool-free strip-down for Clean-In-Place (CIP) flushing, autoclaving, and rapid batch changeover.
Yes. Operating at Up to 100 containers/min, the machine is built on a modular chassis that seamlessly integrates with Filltech SS slat chain conveyors, automatic screw or ROPP cappers, induction cap sealers, and sticker labeling machines for turnkey automated lines.
Yes. Filltech invites customers to ship sample bottles, closures, and liquid/paste formulations to our manufacturing facility at 115, New Modella Industrial Estate, Wagle Estate, Thane. Our engineering team conducts comprehensive FAT trial runs to verify stroke timing and nozzle diameters before factory dispatch.
